The action of 31 July 1811 was a minor naval engagement fought between the Royal Navy and the French Imperial Navy during the British invasion of Java in 1811.

On 31 July 1811, Commander Maunsell of the sloop the Procris discovered a convoy of 40 or 50 proas, escorted by six French gun-boats in the mouth of the Indramayo river. Launching boats they were able to board and capture five of the French gun-boats in quick succession; the sixth blew up. Meanwhile, however, the convoy escaped up the shallow muddy river.
